If you ordered the WUXGA (1920x1200) display on this model, it might not work from the first boot. To be able to use the full native resolution, you'll have to install 915resolution, then set it to patch the video BIOS at boot time.
A good place to start with the startup script is
here. You have to replace the line
/usr/sbin/915resolution 5c 1400 1050 32
with ones appropriate to your machine, as in the following, which are what I use:
/usr/sbin/915resolution 41 1680 1050 32
/usr/sbin/915resolution 42 1920 1200 32
Then make it run at boot, using update-rc.d . Something like
update-rc.d 915resolution start 12 2 3 4 5 . stop 12 1 6 .
will work if you saved the script to /etc/init.d/915resolution . Of course you'll have to edit /etc/X11/xorg.conf (or the XF86 equivalent) to reflect the new resolutions.
